can OPENER.

Application filed October 1, 1921. Serial No. 504,716.

be cut from the end of the can, and hence,-

permits use of the device as a can opener for any ordinary diameter of can.

A further object is to provide a can opener which is of extremely inexpensive construction, which is cheap to manufacture, which is easy to adjust, and which will most efficiently perform the functions for which it is intended.

ith these and other objects'in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a top plan view of my improved can opener.

Figure 2 is an inverted plan View.

Figure 3 is a view in longitudinal section on the line 33 of Figure 1.

Figure 4; is a view in transverse section on the line 4t of Figure 1.

My improved can opener is composed preferably of sheet metal, the parts of which can be cheaply stamped and then assembled and be sold for an extremely low price. 1 constitutes a lever or bar having ahandle 2 at one end and a pivot prong 3 at its other end, said pivot prong being bent or given a general compound curvature, as shown most clearly in Figure 3, so as to position its pointed end 4 in a plane parallel to the plane of the bar or lever 1 so as to permit it to properly function as a pivot when in use.

The bar of sheet metal having parallel flanges 5 adjacent its pivoted end and at its handle end having the metal extended so as to meet and or lever l is formed of a section form a smooth and strong gripping portion, the extreme end of the metal forming the bar or lever extended beyondthe handle portion and perforated as shown at 6, to permit the can opener to be conveniently hung on a nail when not in use.

The bar 1 near the prong end 3, is formed with, a longitudinal slot 7;, through which a cutting blade 8 projects, and is positioned at right angles to the bar 1. This cutting blade preferably constitutes an integral portion of a plate or slide 9 resting on the base.

of bar 1 and of an appreciably greater width than the slot "4'. The blade 8 throughout the greaterportion of its length is of appreciably greater width than the width of the slot 7, said, blade being suitably recessed to accommodate the walls of the slot when in normal position, said slot having an enlarged end 10 to permit the movement of the blade 8 therethrough in assembling my improved can opener.

It will be noted that the blade 8 is triangular in shape or has tapering edges, both edges operating as cutting edges so that the cutter or blade will function with equal efiiciency when moved in either direction.

The plate or slide 9 is formed with a lip 11 at its inner end to which a T-shaped bearing plate 12 and. a lever 13 are secured by means of a single rivet 14-. The T-shaped l'iearing plate 12 has one of its members projected through the slot 7 and its other member, which constitutes the T-head thereof. is bent at right angles to the first-mentioned member and bears against the under face of the bar 1 and cooperates with the knife or blade 8 in maintaining the slide plate 9 against the bar 1 and the parts'in normal position during operation and also during adjustment.

One flange 5 is provided with a longitudinal series of notches or recesses 15 and the lever 13, above referred to, may be moved to one extreme pivotal position and be projected into one of the, recesses 15 to hold the slide9 against movement, In other words, by providing this series of notches or recesses 15 and by providing the blade carrying slide 9 with a pivoted lever 13, I am permitted to lock the parts in any ordinary position of adjustment, so that the knife or blade 8 will be located the desired distance from the pivoted prong 3 in accordance with the diameter of the end of the can to be out, or the diameter of the piece to he cut, will be readily understood.

The operation is follows: The pivot prong 3 is forced through the end of the can, preferalily at the center thereof, and this can be easily accomplished when the bar 1 is held in vertical position and suitable pres sure is applied thereto. The bar 1 is then swung down to a horizontal position and the cutting blade 8 forced into the metal of the can, and while the arm is thus held in position, it is caused to swing or move in the arc of circle with the prong 3 as a pivot, and the blade 8 will make a circular cut in the end of the can.

As it is obvious that cans and circular cuts of different diameter are desirable, I provide an efficient adjustment by sliding knife carrier 9 and also provide an eflicient lock through the medium of the lever 13 and the recesses 15. i

. Various slight changes might be made in the general form and arrangement of the parts described Without departing from the invention, and hence I do not limitmyself to the precise details set forth, but consider my self at liberty to make such changes and alnally slotted bar. a pivot prong on one end of the bar, a slide, mounted on the bar, a knife or blade on the slide projected through the slot of the bar, a bearing member fixed to the slide and projected through the slot,

said bearing member and knife or blade functioning to hold the slide parallel to the bar, said bar having one end of its slot enlarged whereby the knife or blade may be moved therethrough, and means for retaining the blade or knife against movement relative to the slotted bar.

52. A can opener, comprising a bar having flanges in its edges, a pivot prong at one end of the bar adapted to puncture metal to be cutysaid bar having a slot therein, a slide plate on the bar, a cutter or blade projecting through the slot and at right angles to the bar, one of said flanges having a longitudinal series of notches or recesses therein, and a lever pivoted to the sliding plate and adapted to be positioned in any of said recesses and adjustably hold the blade or cutter the desired distance from the prong.
